US Patent Granted to US Navy for “Excess Enthalpy Upon Pressurization of Nanosized Metals with Deuterium”

Thanks to Zephir for providing a link to a newly approved patent to the United States Navy for an LENR process. The inventor is David Kidwell, and the assignee is “The United States of America, as represented by the Secretary of the Navy (Washington, DC)”

Claim 1 provides an overview of the patented method:

“A method for measuring excess enthalpy, comprising: placing a test material in a pressure vessel; heating the pressure vessel to a given temperature; evacuating the pressure vessel; introducing deuterium, hydrogen, or both into the pressure vessel; measuring the enthalpy generated during pressurization; again evacuating the pressure vessel; and measuring the enthalpy used during depressurization.”

In furtherr claims, the test materials are described as palladium, platinum or any combination thereof with a size of , and “oxide support” is described as a zeolite or alumina.

This patent is for what seems to be a very basic process, as deuterium/hydrogen, combined with platinum/palladium have been used in LENR experiments since the time of Pons and Fleischmann, and the USPTO granting this patent might signal something of a vindication for those who have been experimenting with these materials over the years, and reporting excess heat. However, this is not an electrolysis system as Pons and Fleischmann used, but sounds similar to the work of George Miley at Lenuco, who has reported excess heat in a pressurized vessel with nickel nanoparticles .
